Method for preparing edible grease gel with Pickering emulsion as template
ActiveCN105994698AHigh strengthInhibition of oil-water phase separationEdible oils/fatsChemistryOil in water
The invention relates to a method for preparing edible grease gel with a Pickering emulsion as a template. Firstly, an oil-in-water type emulsion with soybean isolate protein nanoparticles as an emulsifier and xanthan gum as a gel enhancer is prepared, moisture in the emulsion is removed with a drying means, and the edible grease gel containing little water is obtained. By comparison with a traditional emulsion, particles can be adsorbed to an oil / water interface of the oil-in-water type emulsion irreversibly, accordingly, coalescence and flocculation of liquid drops and curing of Ostwald are effectively inhibited, and the emulsion can keep stable for months or years. With the adoption of the preparation method, grease which does not contain trans-fatty acids and low-content saturated fatty acids can be obtained and can replace part of solid or semi-solid fat in food. The method has the advantages that operation is simple and convenient, raw materials are safe and environment-friendly and the like.

Disclosed is a conductive composition useful for the preparation of electrically conductive structures on a substrate comprising a plurality of metal particles, a plurality of glass particles and a vehicle comprising at least one cellulose derivative and at least one solid organopolysiloxane resin dissolved in a mutual organic solvent. The solid organopolysiloxane resin acts as adhesion promoter and assists in stably dispersing the metal and glass particles to avoid an agglomeration of such particles without degrading the rheological properties. From such conductive compositions uniform well adherent electrically conductive structures essentially free from defects in the form of cracks, bubbles or coarse particulates can be prepared on dielectric or semiconductor substrates such as silicon wafers in an efficient and cost-saving manner e.g. by screen printing, drying and sintering while inducing only low warping of the substrate. These characteristics render said conductive compositions particularly useful for the fabrication of electrodes of a semiconductor solar cell helping to increase the cell conversion efficiency.

InactiveUS7029700B2Prevents coalesenceMinimize timePowder deliveryPeptide/protein ingredientsSolventChemistry
A process is provided for making dry, micronized particles of an agent, such as a drug. The method includes (a) dissolving a macromolecular material, preferably a polymer, in an effective amount of a solvent, to form a solution; (b) dissolving or dispersing the agent in the solution to form a mixture; (c) freezing the mixture; and (d) drying by vacuum the mixture to form solid particles of the agent dispersed in solid macromolecular material. The micronization in this process occurs directly in a macromolecular matrix and hardening of the particles of agent by solvent removal takes place by lyophilization of the bulk matrix, which stabilizes the drug particles during hardening and prevents coalesence, thereby resulting in smaller final drug particles. The method is particularly preferred for protein agents. The process can be used in conjunction with a standard microencapsulation technique, typically following separation of the agent from the macromolecular matrix. The process yields microparticles having a homogenous size distribution, preferably less than 2 μm, and more preferably less than 1 μm, in size.
